简介：Anovelnanosecondpulsedpowerunitwasdevelopedforplasmatreatmentofwastewater,basedonthetheoryofmagneticpulsecompressionandsemiconductoropeningswitch(SOS).Thepeakvalue,risetimeandpulsedurationoftheoutputvoltagewereobservedtobe-51kV,60nsand120ns,respectively.Theconcentrationsof·OHgeneratedbythenovelnanosecondpulsedplasmapowerweredeterminedusingthemethodofhigh-performanceliquidchromatography(HPLC).Theresultsshowedthattheconcentrationsof·OHincreasedwiththeincreaseinpeakvoltage,andthegenerationratesof·OHwere4.1×10-10mol/s,5.7×10-10mol/s,and7.7×10-10mol/sat30kV,35kV,and40kV,respectively.TheefficiencyofOHgenerationwasfoundtobeindependentoftheinputparametersforappliedpower,withanaveragevalueof3.23×10-12mol/Jobtained.
